Engine oil Castrol or VALVOLINE

Castrol Edge 5w-30 Full Synthetic Euro Car. It carries the BMW Longlife 01 cert.

I recently did my first track day on a day with 105 degrees temps. I went with Castrol Edge 5w-30 and the car did amazing.

I use Castrol for my 05 320 cdi. It meets the extended service oil spec, but I run it as "regular" oil.

I use Valvoline VR1 in my street car and whatever full synthetic that is on sale for my Taurus and Titan.

I use for 2 years Castrol 5w30 its perfect after for top up i use Ina (croatian motor oil) and works perfect

Just swapped over to Valvoline Restore and Protect in my N52 BMW daily driver with 215k miles. I drive a lot and am taking before and after photos inside the valve train. I have exclusively used Castrol Edge A3/B4 for years so I will have a true comparative.

My 2006 WRX has 323k on Castrol 10w-30.

Valvoline is the best oil I can recommend to you. Not even Royal Purple matches it in quality. They have a +75K miles and a +150K miles version of the oil. All of my cars are now on it after trying them all (Mobil, Royal Purple, Pennzoil, Castrol), the only one that effectively prevented oil burn and sealed any leaks in my other cars was Valvoline.

I run Castrol GTX conventional oil in my 1972 Chevy C10 (350). I also ran that in a 1976 BMW 2002 I had in the 80s.

Valvoline oil is good I wouldn't suggest full synthetic it's just a rip off you can get high mileage oil that you can drive for 5,000 or 7,500 miles between oil changes.
